The purpose of the Saturday afternoon “technical talks” is to provide relatively advanced amateurs a forum to discuss various projects that other relatively advanced amateurs are currently working on. While everyone is welcome, of course, please do not be surprised to hear a lot of astronomical jargon, hear about some very complex technical issues and maybe even see a few confusing equations. If you have a suggestion for a subject for a technical during an upcoming convention please click here.
The Saturday afternoon program begins in the Flanders Pavilion at 1 p.m. [PDF version]
Autocollimation testing provides an easy to interpret null test for a parabolic mirror, or any optical system that brings parallel incoming light to a focus. The test is fast and accurate. Autocollimation testing is not new, but is being used or considered by an increasing number of ATM’s today as the interest in better telescope optics and group mirror making workshops is increasing. This talk will show the test concept and discuss: the requirements for an autocollimation flat mirror, important test bench features, how good the test is, and recognizing proper alignment of the test optics, and testing completed telescope assemblies. The similar Hindle sphere test for hyperboloids will also be shown. Whether you are a new or seasoned user of the autocollimation test, you will not want to miss this talk.
There are only two known telescopes remaining of the 50 or more that Galileo built. This presentation will describe our process for replicating high precision museum quality replicas of both the leather covered "presentation" telescope and the paper covered "working" telescope housed at the IMSS in Florence Italy. We will cover our processes for researching the known information on these instruments, highlight discrepancies and describe their resolution by our visiting the originals to make our own measurements and observations. These replicas are displayed at IMSS and other museum exhibits in many countries especially as celebrations of the International Year of Astronomy. We will also discuss how these telescopes are not just optical levers but truly magnificent instruments that serve as excellent examples of 17th century technology and reflect the qualities that are part of our creative heritage and human condition.
Andrew Chaikin, author of "A Man on the Moon," will discuss the experiences of the Apollo lunar astronauts as they became the first humans to explore another world. His newest book, "Voices from the Moon," written with Victoria Kohl, features excerpts from his extensive interviews with 23 of the 24 Apollo lunar astronauts. Chaikin's talk will be illustrated with recent, high-quality scans of mission photography.
The detailed study of magnetic fields in the solar corona requires a telescope with an objective of at least 1.5 meters, a very low level of scattered light, and a large field-of-view. We believe that these requirements are best met by a coronagraph with a singlet lens objective which we are now proposing to build. We will discuss science drivers for the large coronagraph and present the results of engineering studies which show that a refracting telescope of this size is feasible with current technology.
Gerry Logan, who is a long time professional optician and amateur telescope maker, who specializes in complicated telescope designs, will discuss the benefits of constructing a Maksutov telescope and the specific benefits of the Maksutov-Newtonian design.
There will be several talks during the convention which will be geared for people who are new to amateur astronomy and the Stellafane convention: [PDF version]
There will be four 1-hour astronomy workshops for children held in the McGregor Observatory during the 2009 Stellafane Convention (Friday, August 14TH at 11:00 a.m. & 3:00 p.m. and Saturday, August 15TH at 11:00 a.m. & 3:00 p.m.). These astronomy workshops have been held at the Stellafane convention since 1995. Led by Dr. Kristine Larsen, of Central CT State University and member of the Springfield Telescope Makers, each of the four 1-hour workshops includes several activities geared for children ages 5 - 12. Younger children are welcome but will need help from a parent. Each workshop has a different astronomical theme. Please inquire at the McGregor Observatory for the theme for each specific workshop. Due to space limitations, each workshop is limited to 25 children on a first-come basis. [PDF version]
The 12th-Annual Stellafane horseshoe pitching contest is scheduled to begin at 1:30 p.m. Friday near the McGregor Observatory. There will be adult and kid’s competitions. “Astro” prizes will be awarded.
The Jeanne Krzywicki Library, in the McGregor Observatory, will be open throughout the convention, unless the room is otherwise occupied by convention events.
Friday evening, August 14th, at 8:30 p.m. Bob Morse, of the Springfield Telescope Makers, will conduct the informal talks in the Flanders Pavilion.
If you wish to contribute a short talk during this session, you must submit a brief description of your planned presentation with your registration payment or by e-mail here. Talks are limited to 10 minutes and 20 slides. The time limit will be strictly enforced! A 35-mm slide projector, overhead projector, VCR and a digital projector will be available for your use. Note that if you plan to use the digital projector you must bring your own laptop.
Help support the convention and have fun by participating in our raffle. Thousands of dollars in prizes, including books from Willmann-Bell and eyepieces from Televue, are provided yearly by gracious contributors. Tickets are available at the T-shirt table and from designated STM members roaming the grounds. Your dollar goes a long way!

The evening program will begin at 7:00 p.m. Saturday in the hillside amphitheater. Bob Morse, of the Springfield Telescope Makers, will be master of ceremonies.
The Porter/Hartness Museum of Amateur Telescope Making is located in the underground rooms at the Hartness House Inn. Visit the museum on Friday from 3:00 pm to 6:00 pm or Sunday from 9:00 am to Noon. Admission is free. Map & Directions. Many of the items on display are by or about Russell W. Porter, including the Springfield and Garden telescopes. His artwork traces his arctic exploration years to his work on the 200" Palomar telescope, culminating in his famous cutaway drawings. Other items of interest include early 'scopes and mirror making parts. The Hartness turret telescope, with its 10" Brashear objective may also be inspected.
The Swap Tables (located at the NORTHEAST edge of the main camping/parking area on Stellafane East are provided to give amateurs an opportunity to trade, buy or sell their surplus astronomical and telescope related items. They operate from 7 a.m. to 5 p.m. on Saturday, August 15th.
POLICY OF THE SPRINGFIELD TELESCOPE MAKERS At the January, 2005 meeting, the Springfield Telescope Makers, Inc. clarified its policy regarding commercialism and Swap Table sales at the Stellafane convention. For the sake of historical continuity, to preserve the uniqueness of the Stellafane convention and to encourage conventioneers to build their own instruments, the Springfield Telescope Makers, Inc. do not allow commercial exhibits or sales, of any kind, at the Stellafane convention. All sales must comply, in concept, with the above objective but are also specifically subject to the following criteria:
The Springfield Telescope Makers, Inc. may choose to grant a limited exception to the above policies to astronomy related organizations for their fundraising. Any request for an exemption must be made, in writing, at least one month prior to the convention. If granted, the President of the Springfield Telescope Makers, Inc. will notify the requesting organization in writing. Any member of the Springfield Telescope Makers, Inc. has the authority to determine whether a party is in compliance with the established regulations. Any person who is found to be in violation of the stated policies will be required to comply. Failing compliance, the offending party will be asked to leave the convention and may be escorted from the premises by convention security. The Springfield Telescope Makers, Inc. encourages those with questions regarding this policy to contact the Club via e-mail to the Convention Mailbox. During the convention, any questions regarding this policy, the appropriateness of items being displayed, or any information being disseminated should be directed to a member of the Springfield Telescope Makers, Inc.
